Here's his latest numbers after optimizations. From the repo.

     zig: Emulated 600 frames in  0.23s (2880fps)
      rs: Emulated 600 frames in  0.35s (1691fps)
     cpp: Emulated 600 frames in  0.40s (1519fps)
     nim: Emulated 600 frames in  0.44s (1367fps)
      go: Emulated 600 frames in  1.78s (338fps)
     php: Emulated 600 frames in  9.28s (65fps)
      py: Emulated 600 frames in 33.10s (18fps)

That's after Python cheated with native implementation of bitblt while all other implementations are doing it pixel by pixel, which is more correct.

Tables like this routinely lead to over-conclusion. Merely adding -d:lto (which changes no semantics) to the nimble build line boosts fps by 1.27x for me on nim-devel gcc-12 Skylake, making it 1.4x faster than the Rust on the same machine.

Applying BS scaling to the above table, Nim would score 1736, only slightly faster than the Rust. Who knows what little flag tweaks in cpp/rs/zig could similarly re-arrange the numbers?

Now, why is -d:lto (or -d:release) not the default build mode? Well, because it takes time and (some) people already complain about compile times and workflow (sometimes). Trade offs abound almost as much as over-conclusion. ;-)
